To all whom t may concern the extending upperedges :of fthe'jaicket;

Be it known that I, JOHN FLOOD, 'a citiabove the .top 5 is filled withmineral Wool 01j; zen of the United States, residing at Ashtaother non-heatlconducting ma`teri'al. The fbi bula, in the county of Ashtabula and State lower end of the jacket 4- is drawn 'inwardly 60 5l of Ohio, have invented certain new and iseful Improvements in Furnace Attachments; and l do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to lmake and use the same.

This invention relates to attachments for furnaces.

v( )ne object of the invention is to provide an attachment for furnaces whereby the waste heat radiating from the sides of the furnace and from the smoke and heat conducting pipes is retained and utilized for increasing the heat of the furnace and at the 2o same time keeping the furnace room or cellar cool. l

`Another object isv to provide means for controlling and regulating the waste heat collected by the attachment.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will bebmore fully described and particularly pointed out 'in' so the appended claims.

In the-accompanying drawings: Figure 1 is a diagrammatic view of a furnace and portion of a building showing the applica tion of the invention; Fig. 2 is a vertical sectional view of the upper portion 'of the Referring more particularly to the drawings, l denotes a furnace casing, 2 one of the hot air conducting pipes and?) the smoke pipe of a furnace. vThese parts may be of the usual or any desired construction. v

'Arranged around theupper portion of the l furnace casingvl vand spaced asuitable distanceV therefrom is an asbestos heat collecting jacket 4i, the upper end of which projects a"'suitab le distance above the top of the furnace casing and hasarranged ltherein ahead or'top 5, which is set below the uppervv edge of tlie 'jaoketand spaceda suitable distance above the top of the furnace casing,

preferably by .spacing lugs 6, toform a liot air collecting space 7. VThe space formed by and "securely bound or fastened-tol theA outerv side of the casing l by a lowerfclam'ping band 8, while the upper end of the 'jacket' hasengaged therewith an upper-'clamping band 9. At the front side ofthe-furnace' 65 the jacket is cutout and secured to they adjacent'surface ofthe furnace casing'l in any'v suitable mannerv toV provide access top the doors of the furnace. 'In theA sides of` the jacket where the saine is drawnI-in at-fits 'I0 lower edge and fastened to the' lower casing isformed a series of cold air ,inlet ports or passages 10,througli which cold air 7,;

passes and is'heated in the jacket by the heat radiating from the sides of the casing.

The hot-air conducting lpipes 2 one of which is shown inthe drawings, are each provided with an asbestos jacket .'11, said jackets being spaced a suitabledistance from the outer sides of thepipe to forman '80 air space which is open' at the inner end of the jacket or this 'end may be provided with a series of cold airinlet passages. 'In the upper side yof the outer portion ofthe pipe 2 or at the point where the elbow is en# Ag-aged therewith to connect the pipe Vto the heating pipeleading to the registeris formed a hot air inlet'p'assagej1'2 below which in the adjacent end of the pipe is ar.- ra'nged an inclined heat deflecting plate'l by means ofwhich the hot airvfrom the space between the jacket and the pipeis y admitted .and directed V-on through the pipe,

Awhile the hot air from the furnace will lbe prevented from passing out ofthe aperture 12 and will be directed on up through the pipe to the register.'

Connected at one end to the inner end of the pipe 2'and at its'opposite end to the4 jacket 4 is a hot air conducting pipe 14 by loins means of which the hot air accumulating-ini. the upper portion of the space formed be-f A tween the furnace jacket 4 and the` casing 1 1 --isconductedanddischarged into the hot air 1,- l

pipe 2. In the'pipe/lefis arangeda damper 105 .bylmeans of which the assage ofy the f-x". heated air from the space o-rmed by .the l'jacket-et to the hot air pipe2 is cntrolledl".

In the inner end of the pipe 2 .isnalso ar'- ranged the usual heat controllingfdampei"119 16 whereby the hot-air passing through ,the' pipe 2 from the furnace controlled.y

The smoke pipe 3 is also providedi'witli an asbestos jacket 1G which is spaced a suitable distance from the smoke pipe and is open at its inner end and closed at its outer end as shown. Vith the jacket 16 near its outer end is conducting pipe 17 the inner end of which is connected to the jackets: opposite to the hot air' collecting space 7 arranged between the upper end of the furnace casing and the top 5 of the jacket as shown.

By thus inclosing the furnace and the hot-air .and smoke conducting pipes it will be readily seen that all of the heat radiating from these parts Will collected and conducted to the registers thereb nace and reducing the amount of fuel required. It will also be seen that bv inclosing the furnace and the hot-air conducting ,pipes in the'inanner described the furnace will be prevented from heating the furnace room or cellar in which the same is loca'tedA j invention will :be readily understood without j requiring amore extended Various changes in the form proportion explanation.-

and the minor details of construction may be resorted to without depaiting from the' principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus' what Iclaam is: A

l. Anfattachment for furnaces comprisdescribed my invention,

ing a furnace jacket of non-heat conducting material, said jacket surrounding` the furnace casing and spaced therefrom and having at its lower portion air openings, means to secure said jacket to the furnace casing, smoke and hot air pipes, non-heat radiating jackets arranged around the pipes and spaced therefrom, said jackets being open at their lower ends, a hot air conducting pipe connecting the jacket on the smoke connected a hot airA greatly, increasing the heating capacity o the furpipe with the ing and its jacke 2. An attachment for furnaces comprising an asbestos iacket arranged around the furnacev casing and spaced from said casing and having at its lower end air inlet openings, a top arranged in t-lie upper end of said jacket and spaced a suitable distance above the top of the furnace casing, a filling of non-heat conducting-material forming the top of said jacket, a hot air conducting pipe connected to the furnace casing and having near its outer end a hot air inlet passage, a heat detlecting plate arranged below said passage, an asbestos jacket arranged around said pipe and spaced therefrom to form a heat controlling` and conducting space, said jacket being closed atV its upper end and open at its lower end, a hot air conducting pipe to connect the lower' end of said jacket with the upper portion of the jacket surrounding the furnace casing, a hot air controlling damper arranged in said pipe, a hot air collecting jacket arranged Aaround andi spaced a suitable distance from the smoke pipe of the furnace, a hot air conducting pipe to connect the upper end of .said smoke pipe jacket with Ythe furnace casing` jacket, wherebythe hot air collected by thesmoke pipe jacket is conductcdto the space4 inclosed by the furnace casing jacket.

l'n testimony whereof I have hereunto set my hand in presence of two suliscribing witncsses.
